Registered File Types

How do I unregister a file type?

I have a file type extention .z. Did a search for *.z. Found none so I'm assuming that I don't need to have this extention registered.

Thanks.

 

dopey--You did not tell us where/how you found this .z file type.
If it is in Start|Settings|FolderOptions|FileType tab, you can highlight it and click Remove.
If no listing for .z there, then where did you find it?
By the way, there is a .z file type. It involves Unix

Perhaps you will find it under Unix in the FileType tab.

 

Its not listed under the Folder Options>File Types list. I don't have Unix. Can I unregister it?

 

“Found none so I'm assuming that I don't need to have this extention registered.â€

Bit of a leap of faith that, dopey, as it doesn't follow.

.z is associated with compression but with regard which app ..... well, your guess is as good as mine.

If you have a spare moment you may wish to browse through HKEY_CLASSES_ROOT where you'll find all maner of wierd and wonderful extensions but I'd prefer to browse through a telephone directory .

Make a copy of HKEY_CLASSES_ROOT\.z, kill it then diary the event. If whatever time passes without a murmur then you're probably home and dry. I'm afraid our registries are full of stuff which made very little sense in '98 and even less now with all known registry cleaners falling short of the one in our head.

 

Hi Gammaepsilon

Nothing ventured, nothing gained.

I was reading somewhere the other day that most times when an application is uninstalled their file extentions is often left behind. Made a little note to myself to check the file ext. when a little time came available.

So I'm probing again. After researching some I downloaded jv16 power tools which has the option to see all the file types that are registered on the computer. Using the find all files option in Windows I searched for each ext to see what I have on here, and what I don't. I've checked each one that I don't have and put it aside for now. I've saved the list.

I'm using Google to research the ext to get a little more info on what each one is. Don't want to toss one if I need it. Think I'm going to use that site that WelshJim provided. May be quicker.

I posted here wanting to know how to unregister an unneeded file type but jv16 can do that for me.

"with all known registry cleaners falling short of the one in our head. "

Lucky for us they do fall short. The one in our head is the most dangerous. At least mine is.

 

dopey--
I am confused (more than normally)

So?? In other words, what do you mean that

?

 

dopey--Did some "sleuthing" on my own PC, and in the Registry, under HKEY_CLASSES_ROOT I found .z!! If I click on the folder I am told it is involved with WinZip. And the Content Type is "application/x-compress ".
If you think I know what that means, you are wrong. But that seems legit, and I suspect you should not delete it, if that is what you are talking about.
Still wonder where you found .z . Would have helped in responding.

 

John & Jim: AIDA32 will also list file types under Software>File Types and yes Jim is right the file extension ".Z" is listed there as a WinZip file type.

 

Jim

You can read my posts as well as dopey's. I'd already "˜sleuthed’.

 

Hi all

Please remind me not to muck around the registry any more. Thanks.

This experiment was a total disaster.

I deleted about 20 reg type files and all heck broke loose. At least I was able to restore THIS time.

Again I learned what NOT to do.

 

gammaepsilon--

Sorry! You are right, but dopey's are so much more entertaining!!

Where's my Christmas list? Yeah, thats the one. Look for Welshjim. Found him? See the Delete key - wack it!
